looks like Bern is on the money with this one.Hi Jonathan,
easty is right, tiptronic is a Porsche trademark. But the speedshift from MB is only available for the AMGs. The change of gear runs faster than in the normal automatic.
Your first picture shows the automatic gearshift of the SLKs between 1996 and 2000, the second one bewteen 2000 and 2004. In 2000 was conducted a facelift. In both cases a normal automatic is behind it, after 2000 slightly improved, but don't ask for details.
The only difference in use is that you can lock the smaller gears by pulling back the shifter in the 96+ models and pushing to the left in the 00+ models.
A manual mode is availabe for the 171, stock for the AMGs and as a option for the other 7G-Tronic cars.
